This product is a 32-bit microcontroller unit (MCU) suitable for applications that require high-performance processing such as electric motors. The MCU includes the ARM Cortex-M4F, which is a high-performance 32-bit core, and a variety of peripheral devices for motor control. The A34M41x series is equipped with two three-phase PWM generators capable of controlling two inverter motors simultaneously. And an Individual mode optimized for induction heating (IH) has been added. The MCU’s three high-speed 12-bit analog-to-digital converters (ADCs) are capable of processing motor driving information coming in through 24 analog channels. With this function, the MCU can control either two inverter motors, or one inverter motor and a power factor correction (PFC) process, simultaneously. The MCU can have communication with external devices via various interfaces, including UART, SPI, I2C
